1: rating 1 OV protection
Stonger OV protection. Bus voltage wave is small while protection.
2: rating 2 OV protection
Stongest OV protection. Bus voltage wave is big while protection.
While it is valid and bus voltage is reach or over
[FA.05]
, inverter will stop DEC.
LED“00”digit: Protection selection for OV in ACC or constant speed
0: Invalid
1: Valid While bus voltage is reach or over
[FA.06]
, inverter will adjust frequency to protect. It is valid specially for
eccentric load
